Q: Why pair the carbon doors with Lexan windows?

Because swapping doors is the ideal moment to swap glass. When the factory doors come off, replacing the heavy factory glass with UP Lexan side windows brings the total saving to 35.8 pounds, and you still keep working power windows and a full interior. Going further with the full Lexan set, front windshield and roof glass included, reaches 71.9 pounds saved. The doors and Lexan are designed to work as a weight-reduction system together.
